Rock cutting resistance prognosis at the Libous model mining site based on newly developed method

In order to apply technical improvements and innovations on mining equipment, a thorough knowledge of the rock cutting resitance prognosis is essential. The results of specific cutting forces measurement executed on bucket-wheel excavators at Libous brown coal opencast mine (Czech Republic) within selected physical/mechanical and petrographic properties of rock massive determinate possibilities of such prognosis. The produced work represents results of task granted by Czech Grant-in-Aid Agency under registration number 105/98/0166.
